BARREL.

Application filed March 28, 1924. Serial No. 702,634.

. One object of my invention is to improve the construction of barrelshaving a body portion of metal and provided wit wooden heads.

A further object of the invention is to design the barrel so that itwill not be deformed, or collapsed, when rolled on its lower edge, dueto weight of its contents.

A still further object of the invention is to design the body of thebarrel so that a com arativel light head can be used.

, T e barre is intended, primarily, for shipping lime and like material,but it will be understood that it can be used for shipping any materialwithout departing from the essential features of the invention.

In the accom anying drawings: Fig. 1 is a vertical sectional view of thecompleted barrel; Fig. 2 is a vertical sectional view of the barrelillustrating the process of forming the supporting annular ribs for theheads and securing one head to the barrel; Fi 3 is an enlarged sectionalview of one en of the barrel, showin an annular rib prior to bein bentinto al shape; Fig.

4 is a view .,s owing a rib bent into final shape; and Fig. 5 is asectional view of the lower portion of a barrel.

Referring to the drawings, 1 is the body of a barrel made in accordancewith my invention and corrugated in the resent instance. A plaincylindrical-b0 y may be used, if desired. Near each end of the barrel isa deep, internal annular rib 3. These internal ribs sup ort the heads4:, of the barrel, which, in t e present instance, are of wood andgenerall consist of a number of pieces. The woo en heads fit the flanges5 at the ends of the barrel. The flanges are of a greater depth thanthethickness of the heads so that a head-when in ositionas in Fig. 2, isbelow the end 0 a flange,

and, when the. flange is turned over, as

shown in Fig. 1, the head is held-firmly between the annular rib 3 andthe turned over flange.

In making the metallic body of a barrel,

the ribs are partly formed, as in Figs. 2 and- 3, by making anannulardepression 2 in the body near \,each end thereof. When pressure isapplied, the outer edge 6 of the internal flange is flattened to receivea head of the barrel. The other portion of the rib is curved, as shownclearly in Fig. 4, so that the outer edge 7 bears against the outer edgeof the portion 6, supporting rigidly with the body portion thereofresting upon the back of a flange. It will be observed that the loop 3servesnot only to preventthe bending of the head and the crushing of thebody but also serves to directly carry a part of the superposed load andthus reduce the strain on the head. It will be further observed that theface of the rib which en ages the head is wide and flat, thus providingextended contact with the head, and

that the inward turned part of the flange 5 is also wide and flat thusfirml engaging the outer surface of the barrel 'a jacent theentireperipheriy thereof. Inasmuch as the head is griptpe between twoflat faces it is greatly rein orced and the danger of breakage ispractically eliminated.

In assembling a barrel, one flan ed end is placed over a form 9, Fig. 2,an a head 4 is placed in the opposite end of the body of the barrel. andrests upon the partially formed rib 3 at the upper end of the body ofthe barrel. The lower partially formed flange 3 rests upon the form 9.-

T e pressure that is applied to turn in the upper flange 5 onto t e uper head of the barrel causes the partia ly formed flanges 3 at both endsof the-barrel to collapse from the position shown in Fig. 3 to thatshown in Fig. 4. This rocess completes the formation of the arrel. Thehead that is secured to the barrel during this processis the bottomhead. The opposite end of the barrel is shaped so that, when the barrelis filled, the other head can be placed in position within the flangeand upon the formed internal rib, after which the flange can be turneddown onto thehead.

The barrel hereinbefore described can be manufactured cheaply and theheads can be secured in position and fastened with but little effort.that although it can be made of comparatively light weight metal, onaccount of the which it is subjected. The construction is especialyadapted for use with wooden An additional advantage is heads, which canbe secured firmly to each end of the metal body.

I claim:

1. The combination in a barrel of a sheetmetal body comprising near therespective ends thereof two deep internal integral annular ribs each inthe form of an open loop having its peripheral edges in contact witheach other to prevent collapsin and to reinforce the lower edge of saidarrel when rolled or dropped on said edge, circular heads having theirinner surfaces in enga ement with the respective ribs, and annu arflanges formed on the outer ends of the body and bent inward to firmlyenga e the outer surfaces of the respective hea s adjacent the entireperipheries thereof.

2. The combination in a barrel of a sheetmetal body comprising near therespective ends thereof two deep internal integral annular ribs each inthe form of an open loop having its peripheral edges in contact witheach other to prevent collapsing and to re inforce the lower edge ofsaid barrel when rolled or dropped on said edge, the outer faces of thesaid ribs being flat, circular heads having their inner surfaces inengagement with the flat outer faces of the respective ribs, and annularflanges formed on the outer ends of the body and bent inward, the innerface of the said flanges being flat and in engagement with the outersurfaces of the respective heads adjacent the entire peripheriesthereof.
